Hi,
Just been to a job this morning, customer wants power to the garage, no problems there, just one question and I wondered what people tend to do in this situation.
On the back of the house wall is a switched fused spur on a 20A MCB from the consumer unit at the front of the house, its 2.5/1.5 radial. Brand new house, so nice to see they thought of having an option for garage power on the back wall of the house. Does make life easier.
Anyway, what I normally do when I wire someone's shed or garage up is take it out the garage on armoured from a metal clad switch or whatever and terminated the armouring, ill be honest, this is the first one I have come to that is not going to be like that.
The garage end is not a problem, its just the house end.
Option One
Do I feed the SWA inside some 25mm conduit through a terminal box, and terminate the three conductors in the back of the FCU on the inside and disregard terminating the armouring as its already terminated in the garage? This seems ok to me but have a feeling there's a reg somewhere that suggests it should be connected supply end. Although it will be ok and personally cant see anything wrong with it, what do you feel? It would be the neatest job. See photo below of one I did before, but the armouring on that was terminated inside, but this is what the outside would look like.
Or... Option Two
The other option is to take the armoured cable cleated to the wall glanded into a galvanised round joint like below with a rubber gasket. But not sure having never used one, is it possible to take a earth lead off of the metal? Or the other option along these lines is gland it into an adaptable box which I think might look ugly.
or this one I prefer, but don't know if you can get a link from the housing?
What do you think? Thanks.
